Question

我正在尝试解析从国会图书馆下载的MARC文件。我已经使用PyZ3950成功下载了记录，但是当我尝试使用PyMarc解析文件时，我收到以下错误：

Traceback (most recent call last):
  File "test.py", line 13, in <module>
    for record in reader:
  File "build/bdist.macosx-10.9-intel/egg/pymarc/reader.py", line 83, in next
ValueError: invalid literal for int() with base 10: '<PyZ3'

这是我的完整代码：

from PyZ3950 import zoom, zmarc
from pymarc import MARCReader

conn = zoom.Connection('z3950.loc.gov', 7090)
conn.databaseName = 'VOYAGER'
conn.preferredRecordSyntax = 'USMARC'

query = zoom.Query('CCL', 'ti="1066 and all that"')

res = conn.search(query)

reader = MARCReader(str(res))
for record in reader:
        print record.title()

conn.close()

Answer 1

您的陈述：

res = conn.search(query)

返回ResultSet，相应地返回http://www.panix.com/~asl2/software/PyZ3950/zoom.html

r中的每条记录resultSet都包含r.data

中的数据

因此，您必须为每个r.data提供MARCReader，或者将它们全部连接起来。

这将有效：

from PyZ3950 import zoom, zmarc
from pymarc import MARCReader
conn = zoom.Connection('z3950.loc.gov', 7090)
conn.databaseName = 'VOYAGER'
conn.preferredRecordSyntax = 'USMARC'
query = zoom.Query('CCL', 'ti="1066 and all that"')
res = conn.search(query)
marc = ''
for r in res:
    marc = marc + r.data
reader = MARCReader(marc)
for record in reader:
        print record.title()
conn.close()

PyMarc文字错误无效
